print(nested_list[0][0:1]) # [1] 1. 2. 3. 在这个例子中,我们首先使用 nested_list[0:2] 来获取嵌套列表中前两个子列表。然后,我们使用 nested_list[0][0:1] 来获取第一个子列表中的第一个元素。 当然也可以使用负数索引和步长来更灵活地控制切片操作。例如: nested_list = [[1, 2], [3,...

Given a nested list of integers, return the sum of all integers in the list weighted by their depth. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Given the list [[1,1],2,[1,1]], return 10. (four 1's at dept...

Creating a nested list in Python is straightforward. You can define a list and include other lists as its elements. Here’s an example: data=[['apple','banana','cherry'],[7,11,17],['dog','cat','fish']] In this example, the data contains three sublists, each of which contains ...
